System PositionPIR Preferred. PUR Where Appropriate.
Compare PIR and PUR together. BESRIN generally recommends PIR for balanced fire, thermal and long-term stability performance, while PUR remains an option where temperature, compliance and cost requirements are defined. Final performance depends on formulation, density, facings, profiles, joints, details and relevant test evidence.

PIR vs PURTwo Materials. A Clear Comparison.
Compare PIR and PUR core options here. Performance must be confirmed against the selected specification and its test reports.
PIR / RECOMMENDEDPIR: Preferred Option
Typically offers balanced fire behavior, temperature range and dimensional stability for industrial and cold-chain projects demanding long-term performance.
View Details PUR / OPTIONALPUR: Application-Specific Option
Efficient insulation and economy for conventional chilled and frozen storage with defined temperature and compliance requirements.
View Details THERMALThermal Performance
Both are efficient insulating cores. Assess thickness, joints, thermal bridges and aging alongside conductivity.
View Details SELECTIONSelection Guidance
Evaluate PIR first, then compare PUR lifecycle costs where budget, temperature and fire requirements permit.

Cold Chain ApplicationPIR/PUR High-Performance Envelope Applications
Select PIR or PUR for cold-chain applications here. PIR is preferred for demanding fire, thermal and stability requirements; PUR is available for clearly defined temperature, compliance and cost conditions.
Equipment & ProcessContinuous Production & Manufacturing Process
Facing treatment, roll forming, foam metering, double-belt curing, cutting and packing form a continuous process. Equipment and settings are confirmed for each specification.
